Electrochemical Synthesis of New SbTe Zintl Anions by Catholic Dissolution of Sb₂Te₃ Electrodes: Structures of [Sb₄Te₄]⁴⁻ and [Sb₉Te₆]³⁻

A folded Sb₄ ring with terminal Te atoms and cluster containing nine Sb atoms and six Te atoms, the respective polyanions [Sb₄Te₄]⁴⁻ (1) and [Sb₉Te₆]³⁻ (2), form concurrently during the catholic dissolution of a Sb₂Te₃ electrode. This type of electrochemical synthesis certainly extends the repetoire of methods in preparative solid‐state chemistry. ○ = Sb, • = Te. (Figure Presented.)
